  @frederik said in How can I loop through all glyphs of a TTF or OTF font?: pageSize = "A4" Amazing, thanks so much for the tips, @frederik! For anyone coming across this, there was a good discussion of this and of FontTools pens on Twitter: https://twitter.com/typemytype/status/1352985048639799297 Also, I have cleaned up the several scripts in the GitHub repo. using Frederick’s & Just’s advice from both here & the Twitter thread. Have a look and remix as needed! https://github.com/arrowtype/drawbot--loop-through-font-glyphs

  indeed, letters are collected into glyph runs with the same drawing attributes, so if you change a thing (like fill color) then you will get a box for each letter. good luck!

  Hi, hope this helps: # Get your gif routes gifsFolder = '.' # Your gifs directory gifs = ['gif1.gif', 'gif2.gif'] # These are the files I'll use gifPaths = [f'{gifsFolder}/{gif}' for gif in gifs] # Create the paths for your with string formattingx # Create a function to interpolate between gifs def scaleFactor(path, pageNumber, canvasSize): # Get a scale factor to match the canvas size you want gifw, gifh = imageSize(path, pageNumber=pageNumber) factorMeasure = gifw if gifw > gifh: factorMeasure = gifh return canvasSize / factorMeasure def gifTransition(path1, path2): # Canvas and images dimensions w, h = 200, 200 # Canvas size # Define your frames introFrames = numberOfPages(path1) endingFrames = numberOfPages(path2) crossfadeFrames = 12 # Change this value for a longer transition totalFrames = int( (introFrames - crossfadeFrames/2)+(endingFrames - crossfadeFrames/2) ) # Get the total frames by merging the crossfade in the middle # Make a loop for the animation gif1Frames, gif2Frames = 0, 0 gif1alpha, gif2alpha = 1, 0 for frame in range(1, totalFrames+1): newPage(w, h) fill(1) rect(0, 0, w, h) with savedState(): scale(scaleFactor(path1, gif1Frames, w)) image(path1, (0, 0), pageNumber=gif1Frames, alpha=gif1alpha) if gif1Frames < introFrames: gif1Frames += 1 if frame > introFrames - crossfadeFrames/2: # Run the second gif with savedState(): scale(scaleFactor(path2, gif2Frames, w)) image(path2, (0, 0), pageNumber=gif2Frames, alpha=gif2alpha) gif2Frames += 1 if gif1alpha >= 0 or gif2alpha <= 1: # Crossfade transparency gif1alpha -= 1 / crossfadeFrames gif2alpha += 1 / crossfadeFrames gifTransition(gifPaths[0], gifPaths[1]) # Call the function saveImage('~/Desktop/gifCrossfade.gif') # Save your gif

  Thanks @gferreira, I somehow completely missed that when going through the documentation. That's exactly what I need haha. I only have to go through through a single line of pixels, so hopefully the speed won't matter that much.

  This is an old post but this might help someone looking for iteration on gifs, and maybe anyone can tell an interesting fact about it. I've been working with gifs generated via Photoshop and Media Encoder and they crash after the second frame. What has worked for me to fix this problem is to open the gif file with the Mac OS Preview app and rewrite the file, even though this solved my problem it could be great to know if you had a similar experience and how you solved it.

  Hello, @gferreira! I had thought about working word for word ... I didn’t know if it was a good idea ... but it’s really interesting what you coded! I wouldn't have found it alone! thanks! I guess this way the text would never be justified ... but it will be very useful for me! thanks!

  @frederik thank you It worked great now: x, y = 500, 500 resolutions = [72, 18] mfont = '/Library/Application Support/Adobe/Fonts/SansNom-Regular.otf' installFont(mfont) font(mfont) print(listFontGlyphNames()) letters = ['n', 'E'] def pixelar(tx, t, al=True): newPage(x, y) path = BezierPath() path.text(tx, fontSize=500, font=mfont) coords = path.bounds() translate((x - (coords[0] + coords[2])) * 0.5, (y - (coords[1] + coords[3])) * 0.5) drawPath(path) saveImage('~/Desktop/hint_{0}_{1}_aal_{2}.png'.format(tx, t, str(al).lower()), imageResolution=int(t), antiAliasing = al) newDrawing() for letter in letters: for resolution in resolutions: pixelar(letter, resolution, False) pixelar(letter, resolution)

  That's what I suspected. It seemed like the kind of question students would ask and I wanted to make sure the answer I gave was the right one. Thanks, Frederik.

  you can slice a formattedString and keep the formatting: txt = FormattedString() txt += "hello World" sub = txt[0:5] print(sub)
